Assessment of ontogeny in the coenopopulations of Vicia alpestris steven in the territory of Azerbaijan

During the research, the evaluation of Vicia alpestris Steven species based on the study of age and ontogenetic age state in the ontogeny of the coenopopulations has been conducted, and the productivity was studied in the vegetation types up to the formation and association ranks. During the study of the coenopopulation structure, some demographic parameters, including indices of recovery and replacement, age index, coenopopulations types and vitality. The demographic structure was determined by the ratio of different ontogenetic age groups.
